How do you turn 1.282307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.282307 repeating into a fraction, begin writing this simple equation:

n = 1.282307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 2 digits in the non-repeating part (28). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 1282307.2307 (equation 2)

Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.

1000000 × n = 1282307.2307
    100 × n = 1.282307
 999900 × n = 1282179

1282179999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 3 (the GCF - greatest common factor).

n = 1282179999900 = 1282179 ÷ 3999900 ÷ 3 = 427393333300. So,

1.282307 = 427393333300 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 427393333300 is also equal to 194093333300 when expressed as a mixed number.
